摘要:
静态模型用于在发动机各稳态工况下对参数进行动力平衡计算,在发动机地面热试车或飞行试验之前,将发动机参数设定为规定值,已成为型号设计的固定流程。静态模拟是液体火箭发动机系统方案改进和新型发动机系统研制的重要手段之一。基于模块化建模思想和面向对象技术,建立了一套适应大范围变工况调节的发动机组件高精度通用化静态模型库,应用面向对象的仿真工具MWorks/Modelica软件开发了一套适用于液体火箭发动机静态特性分析的模块化建模与仿真软件。该仿真平台实现了现有静态计算成果的标准化、集成化; 突破了传统一型号一模型的局限,极大地缩短了研制周期。
Abstract:
The static simulation model is used to calculate the dynamic balance of the parameters in the steady state of the engine.The engine parameters are set as the specified value before the engine ground test or flight test,which has become the fixed process of the engine design.The static simulation is one important method of improving the system design of liquid rocket engine and developing new engine system.Based on modularized modeling idea and object-oriented technology,a set of static engine static model library with various general components was established,which extended the high precision general static characteristic model of engine to adapt to large range variable conditions.Using the object-oriented simulation tool MWorks/Modelica software,a set of practical liquid rocket launcher modular modeling and simulation software for analyzing the static characteristics of a machine was developed.The simulation platform realizes the standardization and integration of the existing static calculation results,breaks through the limitation of the unified model,and greatly shortens the time of development cycle.
